I doubt it, I think they hired out of some no name information security firm. These people probably are not the group developing the exploits either. I know if I was in their shoes I wouldn't waste my time using anything fancy, but this whole thing reads like some mid level member trying to create documentation to move up the corporate ladder.

I don't want to rush to judge them because not everyone can be at the top and if it works it works. If I can pop a box using powershell, it's way easier than having to develop some kernel level hack. Additionally when anyones 'private' conversations get leaked they always look like a fool because it shows us being vulnerable and asking dumb questions, but a lot of the posts really do remind me more of the sysadmin who learned some python instead of the cutting edge of private industry.
